"We continued to make strong progress with another active contracting quarter resulting in approximately 33 months of additional backlog secured," said Marc Edwards, President and Chief Executive Officer. "Among the new fixtures is a 15-month contract for the Ocean Valiant and a one-year contract for the Ocean Onyx, which we are upgrading and reactivating for the new work. Additional awards were for the Ocean Apex and Ocean Monarch in Australia."

As of January 1, 2019, the Company's total contracted backlog was $2.0 billion, not including $135 million margin commitment from one of the Company's customers.

FORWARD-LOOKING STATEMENTS

Statements contained in this press release or made during the above conference call that are not historical facts are "forward-looking statements" within the meaning of the federal securities laws. Forward-looking statements are inherently uncertain and subject to a variety of assumptions, risks and uncertainties that could cause actual results to differ materially from those anticipated or expected by management of the Company. A discussion of certain of the important risk factors and other considerations that could materially impact these matters as well as the Company's overall business and financial performance can be found in the Company's reports filed with the Securities and Exchange Commission, and readers of this press release are urged to review those reports carefully when considering these forward-looking statements. Copies of these reports are available through the Company's website at www.diamondoffshore.com. These risk factors include, among others, risks associated with worldwide demand for drilling services, level of activity in the oil and gas industry, renewing or replacing expired or terminated contracts, contract cancellations and terminations, maintenance and realization of backlog, competition and industry fleet capacity, impairments and retirements, operating risks, litigation and disputes, changes in tax laws and rates, regulatory initiatives and compliance with governmental regulations, casualty losses, and various other factors, many of which are beyond the Company's control. Given these risk factors, investors and analysts should not place undue reliance on forward-looking statements. Each forward-looking statement speaks only as of the date of this press release. The Company expressly disclaims any obligation or undertaking to release publicly any updates or revisions to any forward-looking statement to reflect any change in the Company's expectations with regard thereto or any change in events, conditions or circumstances on which any forward-looking statement is based.

(1) Average dayrate is defined as contract drilling revenue for all of the
specified rigs in our fleet per revenue-earning day. A revenue-earning
day is defined as a 24-hour period during which a rig earns a dayrate
after commencement of operations and excludes mobilization,
demobilization and contract preparation days.
(2) Utilization is calculated as the ratio of total revenue-earning days
divided by the total calendar days in the period for all specified rigs
in our fleet (including cold-stacked rigs). Our current fleet includes
three floaters that are cold stacked.
(3) Operational efficiency is calculated as the ratio of total
revenue-earning days divided by the sum of total revenue-earning days
plus the number of days (or portions thereof) associated with
unanticipated, non-revenue earning equipment downtime.

Non-GAAP Financial Measures (Unaudited)

To supplement the Company's unaudited condensed consolidated financial statements presented on a GAAP basis, this press release provides investors with adjusted operating income, adjusted net income and adjusted earnings per diluted share, which are non-GAAP financial measures. Management believes that these measures provide meaningful information about the Company's performance by excluding certain charges that may not be indicative of the Company's ongoing operating results. This allows investors and others to better compare the company's financial results across previous and subsequent accounting periods and to those of peer companies and to better understand the long-term performance of the Company. Non-GAAP financial measures should be considered to be a supplement to, and not as a substitute for, or superior to, financial measures prepared in accordance with GAAP.

In order to fully assess the financial operating results of the Company, management believes that the results of operations adjusted to exclude restructuring and separation costs incurred in 2018, costs incurred in the third quarter 2018 for settlement of a previously pending legal claim, the loss on a rig sale recognized in the third quarter 2018, as well as the related tax effects thereof and other discrete tax items, are appropriate measures of the continuing and normal operations of the Company. However, these measures should be considered in addition to, and not as a substitute for, or superior to, contract drilling revenue, contract drilling expense, operating income, cash flows from operations or other measures of financial performance prepared in accordance with GAAP.
